AMUSEMENT DEVICE.' y

Application mea February e, i921.v serial no. 443,523.

To all 'wko/ml it may concern.' Be it known that I, Moms Unsinn, a citizen of the United Statearesiding at Pittsburgh, in the county of-"Allegheny agudv State of Pennsylvania, have invented ceri tain new a-nd useful improvements n 1n AmusementDevices, of which the following' is a specification. v

This inventlon relates to amusement apparatuses and more particularly to such ap-V ysimple construction and "operation which:

may be installed at small cost.

In the drawings: Fig. 1 isa top plan view showing lmy invention applied to a suspended floor-plate.

Fig. 2 is a side elevation of Fig. 1. Y Fig. 3 is a top plan viewv showing my invention used in connection with a floorfplate hinged at one end'. v Fig. 4 is a side elevation of Fig. 8. `F ig. 5 is a top plan view of a modified form of my invention. M

Fig. 6 is a side elevation corresponding to Fig. 5. 4

The construction of my invention shown in Figs. 1 and 2, consists of the'floor-plate 1.

suspended horizontally bythe four horizontalcoil springs 2 secured to the floor joists 3 and the blocks '4 mountedA on the undersidek of the suspended floor. The tension of the coil springs 2 is adjustable by means ofthe threaded nuts 5 and 6 placed on the threaded ends of the springs, so as to keep the floorplate flush with the surrounding floor, when not loaded. f

Two sets of triangular cams 7 are securely mounted on the two parallel shafts 8 and 9 extending transversely below the suspended Hoor and are rotatably mounted'on suitable 4bearing supports 10. The underside of the suspended floor is also provided with metallic contact plates 1l placed above the cams in order to prevent undue wear of the suspended floor and to create a rattling noise when these plates come in contact with the revolving cams. The shaft 8 is rotated by means of' a pulley 12-`driven by va'belt 18 l' actuated by any suitable source" of power.

The rotationv of the shaft vv8 is` transmitted 'i td the shaft 9 by means of the belt 14 -run-v ning on the pulleys 15 and -16`mounted ron the shafts 8 and 9 respectively. 'In' Vorder n g 1,454,715-, PATENT omen.

to counteract' the forward pushingtendencyr of the floor-platebythe-'cams-,the' belt"k 14 `l is preferably crossed so that thetwo setsof1 cams lwill revolve in opposite` direction,

thereby annulling their respective forward push on the Hoor-plate. y

and their location isjsuch that the cams 7 will clear the contact-plates when the floor- Bothcam-shafts are yrevolved continuously plate isf not loaded. lHowever, as soon as al l person steps `uponl the floor-plate, the'latter,l

will sag, `owing to the weight of theperson", and the floor-plate will be forced upgv and down by therevolving cams; this motion be?" ing accompanied by the rattling noise caused f by the striking of the 4cams against the contact-plates. y

In the modified constructiony shown in Figs. 3 vand4, a .floor-plate' 17 is provided.

at one sidev with hinges 18,1 the stationary part of whichV is screwed to theffiooring I19.". The end of the floorplate,opposite tothe hinges, is supported bythe''vertical`ooil1v springs 2O resting on anysuitablepe'rmanent base, and theyfare so proportioned that the floor plate will be flush ,withjthex surrounding floorjwhen-not loaded. Trian; l

gular cams 21 are securely mounted uponA a shaft 22 located transverselyfof'and below the swinging end of theoor-plate. This shaft is; rotatably mounted in the vertical.` 0supports 23 and is located a suii-vv bearin p cient distance below the floor-platetoene able the cams to rotate freelyfbelow their., kcorresponding 'contact plates., 24 whenI the floor-plate is not loaded. 'The shaft 22K-is shown as being driven in this construction by means' of av driveshaft 25, supported by the bearing 25a, andthe bevelgears 2,6 'and' 27 y,securely mounted on the shafts 25 and 22.

in the supports 30, fastened on the underside ofthe iioor-plate. ably mounted on the bearing supports 32 secured on any suitable stationary base. Two sets oi vertical 'coi-1' springs 33, guided by the end plates 34 and 35, are provided underneath and at each end of the floor-plate. The length of these Springs is such. asto keep the floor-plate level with the surrounding lioorwhen not loaded. Symmetrically disposed, on eachside of the supports are two horizontalshafts. 36' and 37 rotatably mounted on the bearing supports 38. Each shaft iszrprovided with asetof triangular cams 39 ande() securely mounted thereon; and so disposed `that when one corner of one set of camsV isI uppermost, the corresponding corner inthe other set of cams will be lowermost.

The-shafts 3,6 and 37, are connectedy together by a belt el running over the pulleys 42 and a3 securely mounted on their respective shafts., In Fig., l5 l have shown the shaft36.A provided with'an extension and a claw-clutchy` 44 for the purpose of connecting this shaft;- to a driving shaft indicatedv by the numeral 45.` For reasons stated before, the floor-plate is 'also furnished on the un.- derside with contact-plates 46. suitably located above eachl cam,- I

order to increase the noise produced by this device, I provide, sometimes,l above 1 one or both sets of cams, the downwardly inclined pliable strips 4j mounted upon the blocks 48" secured on.' the underside of the loor-plate. The cains'will first strike these stripsf which. in turn will. strike the contactplates, thusx doubling the number of noise producing; shocks.

is in thedevices described abovepthe camsf are. able to rotate freely when. the Hoor-plate is, noti'weighted; butr asV soon as a person steps onto,A one end of the plate, it will be depressed. and come into. contact. with therevolving cams whereby the floor-plate will be. moved rapidly up and down.l The passage over 'this door-plate may be guided by suitable railing on each side oi, it so that the` amusementseeker will be forced tov keep on moving` forwarch Upon. passing over the center of -the floor-plate the forward slet oit4 cams will come into play' thereby repeatingv This shaft is rockor irregular shapes suitable for the purposes hereinbei'ore stated. Moreover it is evident that the application of polygonal cams for yproducing alternating-` movements in floorplates be extended almost indefinitely to different arrangements of floor-plates.

It may also, be found desirablein practice to resort to slight changes in construction and arrangement of the detailso my inventiony without departing` l from they field and scope of theappended claims., in this application in which the preferred forms only of my invention are disclosed.

`What l claim is: l

1. In an amusement device of the character described, the combination ot a rockable floor-plate; revolving polygonal cams for producing up and. rdown motions of said floor-plate; means for operating Vsaid cams; means. positioned betweenV said floor-plate and polygonal cams for increasiiig thev noise when said floor-plater is actuated;. esilient means` for supporting saidl floor-'plate above the reach oit said cams when not loaded all oit said means being positioned beneath said floor-plate.I i y 2. ln an amusement device ot the charac'- ter described, vthe combination of a, rockable floor-plate; revolving polygonal cams for producing up and down motions of' said Hoor-plate; means for operating said cams; resilient means positioned between said iioorplate andi polygonal cams for i'ncreasing'the noise when said floor-platei's'actuated; resilient means` for supporting said floor-plate above the reach ot said` cams, when not loaded; all of vsaid means. being positioned' beneath said floor-plate. i l

3.` ln an amusement device .of the character described, the combination of av rockahle floor-plate; revolving polygonal" eamstor producing up and down motions otsaidgiieor plate; means tor operating said cams; means for increasing thenoise whenfsaid yHmr-plate is actuated', said means,consistingr of a downwardlyl inclined pliable strip, secured at one end to the floor-plate and having the other end thereof free to vibrate and'positi'oned between said floor-plate and. polygonal cams;y resilient means for supportingsaid'A floor-plate above the 'reachof'said cams when not loaded; all of said means beingI positioned beneath said' :door-plate. i v i,

In testimony whereof affix my signature.
